Coaxial cables work by allowing electrical signals (usually radio frequency or digital signals) to travel along the center conductor, while the surrounding metal shield blocks external electromagnetic interference (EMI).

An OBD cable, short for On-Board Diagnostics cable, is a specialized communication link that connects your vehicle’s onboard computer system to an external diagnostic tool, such as a scanner, laptop, or mobile interface. I

When I first started learning about vehicle diagnostics, I realized how crucial the OBD cable is – it’s the bridge between the car and the diagnostic tool. The problem is, there are two main types: OBD1 and OBD2, and they’re very different in design, usage, and compatibility.

The first and most important step in choosing the right OBD cable is understanding which OBD system your vehicle uses. Without knowing whether your vehicle supports OBD1 or OBD2, it’s easy to select the wrong cable and end up with a tool that simply won’t connect or function properly.

Once the OBD cable is connected and communication with the vehicle is established, the real action begins. Data starts flowing through the cable, carrying critical information from the vehicle’s internal systems to the diagnostic tool. But what exactly is being transmitted, and how does it get from the car’s control units to a scan tool in your hand?

JST stands for Japan Solderless Terminal, the name of the company that manufactures these connectors. JST is a globally recognized brand headquartered in Japan, known for producing a wide range of high-quality electrical connectors that eliminate the need for soldering.

JST connectors are a series of electrical connectors manufactured by Japan Solderless Terminal (JST), known for their compact size, reliable performance, and wide variety of configurations. These connectors come in different series (like PH, XH, SH, etc.)

I frequently come across JST connectors in consumer electronics, automotive systems, home appliances, LED modules, and industrial machinery. Their compact size, reliability, and ease of assembly make them a favorite among engineers and manufacturers around the world.

In my experience, few connector solutions meet these demands as effectively as JST connectors. Their design and versatility make them a go-to choice for engineers working on compact devices across industries.
